Mantaflow: bake always crashes, cannot be resumed
After realizing that there's no problem if I use Uni Cache (what I usually avoid) instead of OpenVDB I've found an answer myself even for OpenVDB. I don't know why nobody else is experiencing these problems because I'm using the default settings but if so, here's the simple thing I did:
In Blender 2.90 and above the OpenVDB volume format comes with Advanced Settings. Here you can choose Compression Volumes &quot;None&quot;, &quot;Blosc&quot; and &quot;Zip&quot;. The default value is &quot;Blosc&quot;.
After switching to &quot;Zip&quot;, the baking works without any problems. &quot;None&quot; works, too. Only &quot;Blosc&quot; makes all my machines crash.
The difference to Blender 2.83 LTS (which doesn't crash) is, there are no Advanced Settings in that version, probably it uses &quot;Zip&quot; or no compression instead of &quot;Blosc&quot;.
